ROOFING- 0R SHEETING.

i Application filed May 8, 1914. Serial No. 837,183.

and the primary object thereof is to provide a sectional roof structure in which the sections can be telescoped 'at their adjoining ends and interlocked at their adjoining sides, which telescoping and interlocking can be easily and quickly eected and provides joints thatare weatherproof and held securely related.

In the drawings: Figure 1 is a top plan View of one of the blanks prior' to bending same into completed form; Fig. 2 is aside elevation of Fig. 1, the blank being bent into completed form; Fig. 3 is an end elevation of Fig. 1 after it is formed as shown in Fig. t; Fig. 4 is a top plan view of a blank having its side and end both bent into completed form; Fig. 5 is a perspective view of a number of sections in partially connected relation; Fig. 6 is a section taken on the line 6-6 of Fig. 5; Fig. 7 is a perspective view of two uncorrugated blanks in connected position; and Fig. 8 is a perspective view of two blanks in separated relation, and in position ready for connection.

The body of one of the -sections desig' nated l in the drawings is formed with an extended lower side 2 integral therewith, and with an extended end 3 which is also integral with the body. The end extension 3 where same adjoins the body has a somewhat V-shaped projection 5, while the side extension 2 has a cutaway part 6 which is located at the end of body 1, opposite to the end which bears extension 3.

The extension 2 is first folded rearwardly and under on the line 7 to provide a part 7 which is spaced from the under face of body 1, and is then bent on the line 8 forwardly of the lower end of the body 1 and beyond said lower end at 10 to forni a space or pocket 9. The forwardly projecting part 10 provides a ledge or guide which assists in forming the connections between the sections when same are being related. The side 11, of the next adjacent section is snugly received in the space 9 so as to be Specification of Letters Patent.-

`and effective joints are Patented Aug.. i, 1915.

effectively tion.

The ends of the sections are connected or connected, to the adjoining sec- .interlocked by bending the end extensions on line 12 and under the bodies l as at 12 and thence outwardly on line 13 to provide a space or pocket 17, into which the adjacent portion 15 of the adjoining sectlon projects. The end extensions 3 have free portions 21, which project beyond the line of foldv indicated at 12.

In connecting the sections, the plain side 11 ofone section is first inserted in the re- 3 inwardly Y cess or space 9 of the next yadjacent section,

the free side portion of the part 10, engaging the under face of the plain side 11 while the part 7 engages on the upper face of said side 11. Since, as shown in Fig. 7, the part 12 extends beneath the adjacent end of the ledge. 10, the latter will be assisted in being held in close engagement with the plain side 11. The end parts 12 engage one over the other, and the free portions 21 correspondingly seat one on top ofthe other at their adjacent interengaging portions as clearly shown in Fig. 7, in which position of the parts, same are held locked and are provided with weatherproof joints.

The plain or free ends 15 of the sections seat on the upper faces of the parts 21, abut the line of fold 13, and are engaged on their upper faces by the parts 12, the adjacent ends of the parts 21 beingengaged on their under faces by the parts 7 whereby strong formed between the parts.

As shown in Figs. 1 to 6, inclusive, the sections are corrugated, or, as shown in Figs. 7 and 8, the sections may be made plain. IVhen the sections are corrugated, apertures A are formed in the same, as iny dicated in Fig. 1, to prevent buckling of the parts when the fold on line 7 is made.

What is claimed is:

1. A roofing composed of sections each of which has a side extension folded under and then outwardly to provide an outwardly opening pocket for receiving therein the adjacent edge of the adjoining roofing section and also having one end of the folded side extension forming a tongue portion, the first roofing section also having an end ex tension folded under and supporting the outward fold of the side extension to assist in securing the received edge of the adjoining section within the provided pocket,

v an end extension a support tension also `which is guarded vvto 'ngage therewith by the tongue portion, the aforesaid end exeing folded outwardly to provide an outwardly opening pocket adapted to receive the abutting edge of an adjacent roofing section. Y

2. A vroofing'composed of sections each of which hasia side extension folded under and then outwardly to provide an outwardly opening end pocket and also having a V- shaped projection extending inwardly beneath the Side pocket aforesaid and adapted to engage inthe end pocket of theaforesaid adjoining roofing section,v the -end pocket of one 'isection thereby beingsubstantially in alinement with and constitutinga continuation of the end pocket of the adjoining section,jeach end pocket ybeing adapted `to receive the abutting edge portion of an adjoining section beneath the side pocket of the. section. gv,

3. A roofing section composed of bendable sheeting and comprising an outwardly opening side pocket, said bendable sheeting having a tongue portion,. and an outwardlyl opening end pocket projecting beneathV having an extending ledgeportion and forming a support for the side pocket.
